FASTEN ER FOR DOOR S.

SPECIFICATION forming part of Letters Patent No. 529,963, dated November27, 1894. Applicatio filed November 8, 1893- Serial No. 490,373- (Nomodel.)

To all whom it may concern.-

Be it known that I, HORATIO SAQUI, a subject of the Queen of England,residing at London, England, have invented certain new and usefulImprovementsin Bolts or Fasteners for Doors, Windows, and the Like, ofwhich the followingisafull,clear, and exact description.

This invention relates to a fastener for doors of various kinds, such ashouse-doors, railway-car doors, cabin-doors, and the like,

and also window-sashes, &c., and is so designed that it may be used as abolt for fastening the door entirely closed or may be employed for 'thesame purpose as the wellknown door-chain which allows the door to beopened to a certain extent but no farther.

The invention consists in the novel construction, arrangement andcombination of parts as hereinafter fully described, illustrated in thedrawings and pointed out in the appended claims.

In the accompanying drawings-Figure 1 is a face View of the completedevice. Fig. 2 is a plan viewof the same partly in section. Fig. 3 is apart sectional view of aportion of a door with the device attached. Fig.4 is a face View showing the yoke turned so as to hang down verticallyout of the way when not required for use. Fig. 5 is asectionalelevaiion, showing the cam button.

Referring to the above described drawings, A indicates a slotted plateor, yoke pivoted at one end by the pin A upon the bracket B secured tothe door-frame O by screws B or by other suitable means; The portion Bof the bracket B is arranged to turn to the eX- tent of a quarter of acircle upon the fixed part B. The pin or spindle B projecting fromportion B passes through a hole in bracket B in the hollow under side ofwhich it carries the plate B which may be secured to pin 13 by riveting,screwing or otherwise so as to turn with said pin. The projecting pointsB of plate Btalternately engage with the pin B secured in the under sideof the plate B and projecting into the hollow space. This arrangementallows the yoke A to be turned in one direction into the position shownin Fig. 1 and in the other direction at right angles thereto into theposition shownin Fig. 4 in which latter position the yoke A is entirelyclear of the door and the apparatus is not in use. In order to retainthe yoke in either of these positions while allowing it the necessaryplay in that plane only, a flat lug or projection A is provided upon oneof the jaws A at the open end of yokeA which engages with eitherof theslots B or B formed in the face of the bracket B. In Fig. l the lug A isengaged in the slot B and in Fig. 4: it is engaged in the slot B Theyoke A is thus carried entirely upon the door frame. The pivoted portionB is provided upon one face with a projection B and the appropriate jawA with a corresponding recess A and the ends of the yoke A being sprungapart it will be seen that it has a tendency to lie at the particularangle in the horizontal plane due to the respective positions of the lugand the recess. The object of this is to insure the yoke always beinginthe proper position when the door is opened to insure the plate whichthe door carries properly entering the slot in theyoke.

Upon the door D is fixed a plate E screwed or otherwise secured to thedoor. In the drawings the plate E is shown with lugs E through whichpass the screws E by which it is fixed to the door. Plate E has a T-headE which when the door is opened and the end of the plate E is inengagement with the slot of the yoke A projects upon each side of A andprevents parts A and E from being separated. To enable the two parts tobe disengaged when the door is closed recesses A are formed in each armof the yoke near its open end so that they can pass over the T- head Eand thus clear the yoke A from the plate E. i

To fix the door open at certain points a stop E is provided at the endof the plate E and recesses A in the yoke A so that at these points therecess A may slip over the lug E and thus hold the two plates inengagement at those particular points.

The plateE carries the cam-button F which is pivoted at B" so as to turnfreely. In the' under side of the cam button is a recess F adapted tofit over a stud or projection E upon the plate E so that the cam buttoncan only turn in one direction so far as to lie parallel with the plateE. The cam-button is so shaped at or toward the apex F that supposing itto be hanging down vertically in the position of Fig. 1 by pressing theyoke upon it it-will be turned into its horizontal position and thenwhen the yoke is passed over it it will fall back again into a positionapproximately such as shown in dotted lines in Fig. 1, this movementbeing automatic by reason of the buttom being overbalanced the tail Fbeing heavier than the other end. Upon the yoke A are two stops Gagainst one or both of which the cam button bears when turned into thevertical position shown in Fig. 1; the faces G of the yoke A which leadup to the stops G being inclined so that when the cam button is pressedhome against the stop G it firmly holds A and it together, and can onlybe itself turned out of that position by the exercise of considerablepressure.

I have described the bracket l5 as being fixed upon the door frame andthe plate E as being fixed to the door but these positions may bereversed if desired.

The operation of this apparatus is as followsz-Supposo the parts to hein the position indicated in Figs. 1 and 2. The door would be secured asby a bolt and could only be opened by the turning of the cam button F.

into the horizontal position, and the lifting of the yoke over or pastthe cam button. This being effected, if the yoke A is allowed to restwhere it naturally would under the influence of the spring regulators Aand B", and the door were opened it could only go as far as shown inFig. 3 because the plate E would enter the slot in the yoke and the headE engagingthe yoke upon each side of the slot would prevent the twoparts from becoming detached and when the position shown in Fi 3 wasreached the door could not be opened farther and the apparatus would actin a manner similar to that of the ordinary chain. If when the cambutton has been turned the plate A be turned back as far as it will goor at all events sufficiently far to entirely clear the plate E and itshead E the door can be freely opened as the two parts A and E would beentirely separate. \Vhcn this is required the yoke may be turned aroundand allowed to hang down as shown in Fig. 4, the lug A then engagingwith the slot B of the plate B and thus preventing the yoke fromcatching upon the door.

As a further security when i the apparatus is to be locked the plate Itmay be provided at one or both ends with loops H, H adapted to passthrough the slot in the yoke A and by placing a padlock through one ofthese loops the door can be securely locked. If it be desired to lockthe door in its open position of Fig. 3 a padlock may be placed throughthe loop 1-1 behind the yoke A and the door then cannot be closed as thepadlock will prevent the yoke from moving over the plate E.

As it is sometimes desired to place this device upon the outside of adoor, say a streetdoor, it is desirable to be so able to fasten or lookit that it cannot be tampered with and also to so arrangeit that thescrews by which the parts are held to the door or framework cannot beremoved until the apparatus is opened. For this purpose I may providemeans of locking the parts which may be offcctcd in various ways. Forexample, a hole may be made through the cam-hntton in any required partand through said hole a padlock may be placed so that even if the cam beturned the yoke cannot be lifted and the fastening is thus maintained;or one or more loops may be provided at any part or parts of the bracketplate and the padlock placed through as before; or, again, a lock may beplaced within the button or locking plate in such a manner as to securethe parts, when the lock is placed in the cam it may be arranged tooperate by preventing the cam from being turned at all. .By securing thebracket plate by screws passing through lugs exten ding therefrom thelock may be arranged to cover these screws so that they cannot be got atuntil the yoke is lifted which cannot be done when the device is locked.Similarly the screws holding the yoke bracket upon the frame may bearranged so as to be covered by the yoke or other portion of the device.The screws however maybe otherwise placed or arranged so long as theyare protected when thcdevice is closed.

To secure the screws on the bracket plate from being withdrawn when theyoke is lifted I may provide means whereby they are protected and I maypreferably employ lugs in such position on the bracket plate with relation to loops thereon or to a hole or holes in the cam-button and handlethereof and when for example I employ a padlock through such loops orholes in the cam-button the screws in the lugs become thereby protectedor I may employ other suitable locking devices whereby such screws areseen red against tampering when protected by the yoke.

When using this as a simple fastener the yoke may if desired bedispensed with and a slotted plate secured upon one of the members to befastened he slipped over the cambutton which then fastens itself asabove OX- plained.

hen it is desired to prevent any absolute locking of a door altogetherbut only to provide against the door being opened farther than thebracket plate will slide in the slotted plate or yoke I may dispensewith the cam-button and em ploy other suitable means when required. Imay employ a spring or other suitable retaining device to hold the yokein the required position but which will not prevent the door from beingopened as far as the bracket plate will slide in the yoke and I mayemploy such spring or other devices in combination with or actuating ahell or other signal or alarm.

To prevent rattling of the door when fastened I may provide inclinedsurfaces upon the yoke where the cam-button bears upon it preferablywith stops to prevent the button from turning too far.
